SINGING HISTORY

At a “shape-note singing” session, singers sit facing the leader, who stands in the center, and sing 16th-century choral music a cappella. The sing-along style is seen as the precursor to gospel music and was popular in the American South, especially among Baptist sects that eschewed instruments other than the voice. The four-part harmony music was later revived in the North in the 1960s folk music movement, and was recently heard in the film “Cold Mountain.” Though the shape-note songs – also called “Sacred Harp” songs, after a popular hymnal – originated in the Christian church, the singing is now a social event that draws people of all backgrounds and skill levels. Saturday, 3-6 p.m., the Living Room, 154 Ludlow St., between Rivington and Stanton streets, 212-533-7235, free.
